Marek, I didn't explain that right. The failure is that dwc3_glue_probe gets passed usb3_0:usb@32f10100 USB (controller dev) and tries to find usb3-phy in the phy-names prop of that dev where-as the phy-name node is in the usb_dwc3_0:usb@38100000 phy child of the controller instead However, I still wonder if I'm missing a patch that deals with this or if something just changed between testing your patch series and now.
